FILTER.

I Specification of Letters Patent. Patented Man-4L, 1913,- Applicationfiled June 29,1910, Serial No.

To all whom it may concern: I

Be it known that I, HARVEY F. MARAN- VILLE, .a citizen of. theUnited-States,-residing at Akron, in the county of Summit and State ofOhio, have invented a certain new in Filters, of

exact description, reference the accompanying drawings.

This invention relates to oil filters and, in the embodiment shownherein, has in view the filtering of oil for us with motor vehicles. Inthe form of filters shown herein, means are provided whereby thesediment may be effectively removed from-the -oil, the oil washed,cooled and stored for distributionz made for preventing, in a movlngvehicle, any access oft-he water by means of which the oil iswashed andcooled, into the storage chamber of the filter. 7

With the accomplishment of the foregoing objects in view, the inventionmay be consisting. of the combibeing had to nations of elements andparts embodied in the claims hereto annexed and illustrated in thedrawings forming part hereof,

where1n Figurel represents a verticalsectional view through a filterconstructed in accord-' ance with myinv'ention; Fig. 2 is a sideelevation of trating the manner in which the filter is used inconnection therewith; and Fig. 3 a

the hood and supported in any suitable manner, is a multi-cylinderengine, the'individual cylinders o which are shown at 4. The engine base'is substantially the same as shown in the aforesaid application,comprising generally an lower detachable section carrying a receptacle 6provided with a filling connection 7, said receptacle communicating witha pump 8 which is connected by the pipe 9 with the upper part of thefilter, designated gen.- erally by the reference numeral 10. The pipe 9is conveniently threaded into the central boss 11 carried-by theremovable of the central boss In addition, provision is ing 26.

a Inulti-cylinder engine, illus-" by reference charac- 'plate 35,

upper section 5 and apipe is shown as extending through this boss andthreaded in turn into a boss 13 on the cover 14 of an internal strainerhavin cover 12 of the filter tank. The end of this a perforated metalliccylindrical wall 15- extending between said cover and a sediment pan 16and forming a screen. Outside 11, the cover 12 is pro-. vided with acircular rib.17 forming a support for the upper end of the perforatedmetal screen 18 located outside of the metal screen 15. The lower end ofthe screen 18 engages a circular rib-19 .Wardly from a plate 20. Thisplate is pro vided with a central intern-ally threaded boss 21 whichreceives the upper threaded end of a pipe 22.

N ear'its outer periphery, the cover 12 is provided with a circular rib23 forming a support for the upper end of-a perforated projectingupmetal screen 24, the lower end of which engages the up-turned flange,or rib 25 at the outer periphery of the plate 20. The cover 12 isconveniently secured to the casing 26 by means 'of bolts 27 extendingthrough a flange 28 at the outer periphery of the cover and thehorizontal flange 29 of an angle'iron which is secured to the Betweenthe casing 26 and the screen 24 a space 30 is provided and the upper endof the cas screen 24 -is covered with a fine-meshed cloth 3-1.

The bottom of the central tube 22 is sup ported by a plate 32 of lessdiameter than the diameter of the casing 26 and sup: ported, from thebottom 33 of said casing, by'means of a perforated cylindrical metallicscreen. 34, th said plate. The upper end of the t-ube'22v is provided,below the plate 20 and above a with a series of perforations 36; 35issoldered to the tube 22 and to an annular wall 37 located within thecasing'26 and in proximity thereto, a pas sageway 38 being formedbetween the plates 20 and 35.

39 'denotesa plate located below the plate 35 and extendingsubstantially parallel therewith and from the wall 37 to the tube 22.,The plate 39 is provided, adjacent to the tube 22, with a plurality ofopenings A sleeve or casing 40 projects upwardly from the plate 39,outside the openings 39, and forms a vertical passageway with the tube22. The upper endof the casing 40is provided with a downwardly The platee screen being carried by with the plate 32. This plate is preferablythe wall of the casing corrugated, as shown and extends outwardly fromthe tube 22 and has its outer edge spaced a short distance from thecasing 26 to form a narrow passageway 45 therewith. 46 denotes afrusto-conical deflecting plate which is also preferably cgrrugated andthe upper end of which is secured to the tube 22., as by soldering, thelower end extending downwardly nearly as far as the plate 32 and spaceda comparatively short distance from the casing 26 to form a passageway47 therewith. The filling tube 48' extends upwardly from the spaceformed below the late 44 and is provided with a plug 49.. t its lowerend, the casing 26 is provided with a clean-out opening provided with aplug 50, for the removal of any matter that in ay settle at the bottomof the easing through-the washing of the oil. I

The portion of the apparatus which is provided above the plate 20 is forthe purpose of filtering the oil which is pumped through the pipe 9. Thespace between the perforated screens 18 and 24 is filled with a suitablefiltering material, as bone black, and the cloth 31 is applied totheouter surface of the metallic screen 24. The annular receptacle formedbetween the cylindrical casing and the casing 37 is provided with aninternally threaded boss 51 secured to 37. A similar boss 52 is attachedto the casing 26 and a nipple 53 is threaded through both of saidbosses. The outer end of the nipple is detachably connected to amanifold 54, from which pipes 55 extend through the wall of the uppersection 5 of the engine base. As will appear from Fig. 1, the outletnipple 53 is of less sectional area than the pipe 9, a convenient sizeof these pipes being 4;" for the pipe 9 and i? for the nipple 53. Thepurpose of this construction is to cause the oil to leave the storagechamber 56 less rapidly than the oil is fed into the filtering chamberand thus preserve a level of oil in the chamber 56 when the engine isrunning. Having the pipe 9 and nipple 53 of different areas. is but oneway of-accomplishing the desired result; other means might be used whichwould be within the scope of my in-- vention.

The lower portion of the casing 26 is a water chamber, receiving waterthrough the filling tube 48. The level of the water in this chamber isindicated by the dotted line 57. In winter a non-freezing mixture ofglycerin and water may be employed.

cooled in passing The oil used in an explosive engine becomes greatlyheated, and hence the water which washes the oil in the filter willlikewise become heated. For the purpose of cooling the oil and water, Iprovide air pipes or conduits 58 which pass through the water chamber.These conduits may assume any form' desired, but are so arranged thatthe water and oil will flow all around the same, while the air whichpasses through file pipes or conduits will conduct away the eat.

The annular chamber formed between the c lindrical wall 40 and the wallor casing 3 is a receptacle for the filtered oil, the bottom of which isformed by the plate 39.

59 denotes a age which is connected by means of a suita le pipe 60 withthe filtered oil or storage chamber 56 or receptacle in the casing 26.

With the parts arranged as above described, the operation is as follows:Oil accumulating in the receptacle 6 is pumped through the pipe 9 intothe first filter chamber. The oil is partly filtered in the first filterchamber in passing through the screen 15 and much of the sedimentremoved therefrom; thence it passes through the screens 18 and 24 andthe bone black filling therebetween, thus being nearly completelyfiltered and having the fats and heavy substanbes removed therefrom. Thefinal filtering is accomplished by oil as delivered from the crank caseto the filter is hot, and the hot, clean oil flows through thepassageway 38, openings 36 and tube .22 into the space beneath the plate'32. It passes under pressure through the screen 34, around the outeredge of plate 32, where it divides, part passing through the openings 46in the plate 46- and artthrough the space 47 provided between t eperiphery of the plate 46 and through the peripheral passageway 45 abovethe water level, beinglefliciently washed and corrugations in the plates44 and 46'facilitating this result. Still under pressure it risesthrough the openings 39 into the annular passageway formed between thetube the cloth 31. The

the casing, finally passing rough the water, the

22 and the cylindrical wall 40 and overflows into the storage chamber56. The par ticular arrangement of the plates 32, 44 and 46 provides atortuous oil, the effective length of which is increased by thecorrugations in said plates, an

causes the oil to be effectively washed and cooled in its passagethrough the water. The baflles 41,42 and 43 prevent any water from beingthrown into the storage chamoperation of the autopassagewa'y for the idisconnecting the' sec- I ber 56 through the vertical movement givenchamber :defin'edby the'coveril t, pan 16 and' screwing. thelattenfrom-the tube 22.

,-As previously stated, a; in-ixture of water and glycerin may beemployed in the 'washing and, cooling chamber,- 'suc h"-m ixture forminga, non-freezingmixture. ,I-Iowever as some. users "are aptt-Quseiwaterfalone in such, chamber, I provide means whereby, in the'GVGILt-Qfthe freeiing oi the water, the- 'oper at-ion of the apparatuswill not be stopped. A suitable. number ofitube's. 61'

are provided which extend-upwardly from' the' plate into the. annularpassageway 30, the upper ends' of these .tubes being a short distancebelow theflange' 23 -o'f.'the-- cover,-

IhesIetubes may be conveniently cast with.

or 'formed 'with the casing 37 Should the flow of" oil into the; waterchamber be checked or, hindered 101, for any other reason, the zoilaccumulates in the annular pas-J sageway 3Q, suchoil will overflow thevtops of the tubes and, thus enter. the storage and di'stributing chamber56, which twill enablev the supply of filtered oil to; be maintained,-
